Show your solution clearly. Thank you!

1.) Show that the triangle with vertices at A (-2, 4), B (-5, 1), and C (-6,5) is isosceles. 2.) Let G be the function which is the set of all ordered pairs (x, y) such that V = x-3 Find the domain and range of G, and draw a sketch of the graph of G. 3.) Find lim x +2x+3 -4 4.) Find the derivative of the inverse of X
